A recent UK study published in Plos One found that popular poodle crossbreeds, like cockapoos and cavapoos, exhibit more behavioral problems than their purebred parent breeds. Researchers at the Royal Veterinary College analyzed data from over 9,000 dogs, collected via owner questionnaires, focusing on cockapoos, labradoodles, cavapoos, cocker spaniels, labrador retrievers, cavalier king charles spaniels, and poodles. The study assessed behaviors across twelve scales, revealing that cockapoos showed more aggression, fear, and separation-related issues compared to both poodles and cocker spaniels. Cavapoos also displayed more undesirable behaviors than cavalier king charles spaniels. Labradoodles scored better than poodles, but worse than labradors on several scales. The study highlights the importance of thorough breed research before acquiring a dog to avoid misinformed decisions.
